Bob Saget guest starred on an episode of “Law & Order: LA” on June 27, playing a pornography producer who finds himself surrounded by murders. Spoiler alert: as it turns out, Saget’s character is the murderer.

“I’m a porn producer, how could I not be the murderer?” he told The Wire the day the episode aired.

He joked that when the show’s creators cast the role of the murderous smut producer, they immediately went looking for a “Bob Saget type”—you know, a dirty, sleazy middle-aged man with some acting chops. 

If you’ve seen Saget’s recurring role on HBO’s “Entourage,” in which he plays a fictionalized version of himself, this probably seems like a natural fit. Or if you’ve seen his notoriously filthy cameo in the 2005 documentary “The Aristocrats.” Or, for that matter, if you’ve seen his standup routine over the last decade or so. 

But how and when did Bob Saget become typecast as a sleazebag? For anyone 25 or older, Saget is still primarily remembered for his role as the painfully prudish dad on “Full House” or the endearingly dorky host of “America’s Funniest Home Videos.” Saget starred in both programs for eight years in the late 1980s and ’90s. 

The truth is, Saget has always been a dirty comic. And while his family sitcom success produced wealth and stardom, he feels more at ease making poop and dick jokes. The fact that he’s forever enshrined as the fastidious, dust-busting Danny Tanner only adds to the shock value. Most fans have come to embrace the obscene Saget.

“Everybody is pretty much in on the joke now,” he said.

Seacoast fans can get in on the joke on Saturday, July 9, when Saget performs standup comedy at the Hampton Beach Casino Ballroom. But don’t expect a clean and wholesome act.

The shift in Saget’s public image began in 1998 when he made a cameo appearance in the movie “Half Baked” and delivered the line, “I used to suck dick for coke.” That same year, he directed the comedy “Dirty Work,” starring Norm MacDonald.

But his persona took a harder left turn with his profanity-laced, incest-filled, scatological tirade in “The Aristocrats” (2005). In a documentary comprised entirely of famous comedians proffering their own versions of the world’s dirtiest joke, Saget may have taken the cake for the single filthiest performance.

“Entourage” flew with the new and uncouth Saget, casting him as a bong-toking, sex-obsessed egotist who once lived next door to the protagonist. 

“What a bastard character, with my own name,” Saget said with a laugh. “I wish he didn’t have my name, because that really is not me—although I have been at my pool at my house in a black robe, unshaven, smoking a cigar, and my girlfriend looked at me and said, ‘OK, that is you. Sometimes that is you.’”

Saget cemented his comedic makeover with his 2007 HBO special, “That Ain’t Right,” erupting with jokes about sex and bestiality and all things taboo. He may have also set a new record for most f-bombs dropped in a single routine. 

“Don Rickles actually said to me, ‘I saw your last special, Bob. It was great. You left out two fucks,’” Saget recalled.

Now 55, Saget is in the process of compiling material for a new TV special. The next one will be toned down, he said, although probably not G-rated.

“I think it’s cleaner than my last special,” he said. “I’m not saying ‘fuck’ as much, which is gonna be so nice for the listeners.”

Among his newer bits are a number of “love songs,” with sweet and tender melodies belying the sordid lyrical content. 

“None of them are in good taste,” he warned. “One of them is about my relationship with an elderly lady in a nursing home, kind of a ‘Harold and Maude’ kind of tone. And of course, it doesn’t end well.” 

Another song that’s become a staple of his live shows is “Danny Tanner Is Not Gay,” which he performed on the HBO special. It was one of several references to his days with “Full House,” the show that launched the careers of the Olsen twins and also put costars John Stamos and Dave Coulier on the map. Saget often pokes fun at the show, but it still clearly holds a dear place in his heart.

“That show is a part of culture. John, Dave and I talk about this,” he said. “That show’s gonna last forever, with those kids and the way it was done. It was a beautiful two-dimensional sitcom with nothing but love at the heart of it.”

Just like his character on “Full House,” Saget has three daughters, all of whom grew up around comedians. Hanging out on the set of “Dirty Work” as young girls, they met stars like Chris Farley, Chevy Chase, Norm MacDonald and Artie Lange.

Saget said he regrets some of the jokes he’s made about his daughters, and he makes sure kids are not allowed into his shows.

“I tell them, 18 or with a good fake ID,” he joked. “If there’s 9-year-olds, I won’t do the show. I’ll have to take them backstage and I’ll give them some signed T-shirts and, you know, some alcohol. I’d rather get them drunk than have them hear what I’m saying.”  

The diverse range of Saget’s work over the last five years has been impressive. He wrote, directed and produced the 2006 mockumentary “Farce of the Penguins,” which was narrated by Samuel L. Jackson. He even did a stint on Broadway playing the lead role in the musical “The Drowsy Chaperone.” 

Last year, he produced a comical documentary series called “Strange Days with Bob Saget,” in which he hunted for Bigfoot in the Pacific Northwest, joined a frat at Cornell, and rode with a motorcycle club (in a sidecar).

Saget has performed at the Casino Ballroom once before, in 2006, and he said he looks forward to returning. The mere mention of the Hampton venue’s title provoked a devilish cavalcade of scrotum jokes.

“I’m gonna bring a new meaning to the words ‘ball room,’” Saget said. “There will be no ball room when I am done. I’m gonna pack it out.”

This reminded him of a joke he recently improvised onstage, inspired by the Ballroom. He jotted it down on a post-it note to refresh his memory. 

“When I was born, my testicles were huge. They were gigantic. They were bigger than my body. I eventually grew into them,” he said, giggling at himself. “They were like a Hoppity Hop. I would just, like, bounce around.” 

Saget admits that most of his jokes reflect the potty-mouthed humor of a 12-year-old boy, but he can’t help himself. And, no matter how vulgar and juvenile the comedy gets, most of us can’t help laughing along with him.

“I’m not doing it for any reason except I find it funny,” he said. 

The show begins at 8 p.m. on July 9 at the Hampton Beach Casino Ballroom, 169 Ocean Blvd., Hampton, 603-929-4100, www.casinoballroom.com. Tickets are $25 to $45.
